Figuring out which sports to introduce to your child is a lot harder than it was for your parents. To start with, kids (and the parents who drive them) have a lot more sports to choose from than we did, and they're starting to play when they're much younger. Your first step should be to ask your son what his favorite sport is. There's a good chance that it's the one you're most interested in. But as I'm sure you've noticed, his tastes can change quickly, and what he's obsessed with today might bore him to tears tomorrow.
